Title: Multi-stage packed gas washer - with separate liquor recycle to each stage and fresh liquor feed to topmost
Inventor: KLEMM WALTER DIPL ING
IPC: B01D47/14
Filed: 1974-10-25
Abstract: Process for washing dust from gases uses a wash liquor recycling round a packed column section of which there are two or more one above the other, gas flowing vertically upward. Each section has separate liquor draw off and recycle and liquor cascades downwards from one section to the next, fresh liquor being fed in at the top. This is sprayed upwards onto a knitted mesh pad above the top section. Liquor is collected by draw off into vessels below. Liquor from the upper section cascades over a baffle into the vessel for the lower section. A droplet disentrainer in the form of wet film separator is mounted on the top. To scrub dust out of gas streams. Co-current roasting of gas streams for dust removal has been shown to save wash liquor. However it is limited to processes in which only slight gravity varus-occur as this effects the efficiency. By using several stages in counter-current with recycle, the disadvantages are overcome and a marked sawing of liquor obtained.

Title: Thermal intercept system - modified modulating disc permits target elevation determination using chequered pattern in image plane
Inventor: PUSCH GUENTER DIPL ING DR ING
IPC: G01S3/781
Filed: 1975-03-10
Abstract: A modulation system for a thermal interception system, in which target and background are distinguished by movements of a chequered pattern in the image plane, with provision for determination of the vertical coordinate of the target. The phase of the modulated signal is compared with that of a signal derived from the rotating modulator disc to determine the azimuthal position by a brief interruption of modulation, at a time independent of the vertical position in the original invention since the interrupting edges were always perpendicular to the direction of movement of the disc. The determination of vertical position is effected using an edge at an angle to the direction of movement. The ratio of the time of interruption to time of presence of the modulation can be used to indicate the vertical position of the image point.

Title: Parameter stabilisation device using wheatstone bridge - achieves balancing of bridge using variable bridge voltage to compensate for changes in measurement resistance
Inventor: SICK HINRICH DR
IPC: G01K7/24
Filed: 1975-03-15
Abstract: The system is used for stabilising a resistor which is dependent on temperature, light intensity or an electric or magnetic field. The resistor is included in a Wheatstone bridge, and the bridge voltage is regulated to keep the bridge in balance. As the parameter which affects the variable resistor is changed, so the bridge voltage is altered, and this voltage is taken as the measurement value. Where a resistor which is affected by variable magnetic field is used, a variable magnetic field may be used for balancing the bridge. The bridge may have two fixed resistors (R2, R4) and two variable resistors (R1, R3).
